rOn September 28, 2000, BLS issued revised CPI data that correct for the impact of a recently discovered software error. Revisions affect the U.S. city average and the regional and metropolitan all items indexes as well selected lower level indexes. Indexes were revised for both the CPI-U and CPI-W and cover the period from January 2000 through August 2000.
